Problems solved by technology

However, due to the low reproduction rate and slow growth rate of yellow catfish in natural waters, the wild yellow catfish caught in natural waters can no longer meet the market demand. Therefore, yellow catfish is artificially raised as an economic fish in various places
At present, the artificial cultivation of yellow catfish in Guangdong Province, Zhejiang Province and other regions has a certain scale, but there are still some technical problems in the artificial cultivation of yellow catfish, and the breeding technology is not yet mature.
Now using the fish feed on the market to feed the yellow catfish, the survival rate and weight gain rate of the fish are low, and it is easy to cause the body color of the yellow catfish to become lighter (whitening), and it is easy to cause the body color of the yellow catfish to become lighter (whitening) ), and the yellow catfish in the natural water body, due to ingesting a large amount of algae and plankton rich in carotenoids, the body color is brighter, under normal circumstances, there are black spots on the side of the body, and the rest of the body is yellow

[0021] Carry out throwing something to feed yellow catfish experiment in the pond, the average specification of yellow catfish is 2.1 grams / tail, pond area is 1 mu, stocking density 4000 fish / mu, last 60 days, throw something and feed the weight percentage of each component of compound feed For: fish meal 45%, meat and bone meal 5%, flour 15%, corn 8%, soybean meal 8%, rapeseed meal 3%, fish oil 2%, corn gluten meal 10%, multivitamin 1.0%, multimineral 1.0%, immune enhancement 0.1%, hepatoprotective agent 0.2%, choline 0.2%, calcium dihydrogen phosphate 1.5%.

Embodiment 2

[0023] Carry out throwing something to feed yellow catfish experiment in the pond, the average specification of yellow catfish is 2.1 grams / tail, pond area is 1 mu, stocking density 4000 fish / mu, last 60 days, throw something and feed the weight percentage of each component of compound feed For: fish meal 40%, meat and bone meal 5%, flour 17%, corn 6%, soybean meal 13%, rapeseed meal 3%, fish oil 2%, corn gluten meal 10%, multidimensional 1.0%, multimineral 1.0%, immune enhancement 0.1%, hepatoprotective agent 0.2%, choline 0.2%, calcium dihydrogen phosphate 1.5%.

Embodiment 3

[0025] Carry out throwing something to feed yellow catfish experiment in the pond, the average specification of yellow catfish is 2.1 grams / tail, pond area is 1 mu, stocking density 4000 fish / mu, last 60 days, throw something and feed the weight percentage of each component of compound feed Contains: fish meal 32%, meat and bone meal 5%, flour 16%, corn 8%, soybean meal 14%, rapeseed meal 4%, fish oil 2%, corn gluten meal 15%, multidimensional 1.0%, multimineral 1.0%, immune enhancement 0.1%, hepatoprotective agent 0.2%, choline 0.2%, calcium dihydrogen phosphate 1.5%.

[0026] Embodiment effect is as follows:

[0027] Example 1

[0028] The body weight gain rate, feed coefficient and survival rate of the yellow catfish were 523.86%, 1.28 and 83.1% respectively. The body color of the yellow catfish in the test was normal, and the weight gain rate of the yellow catfish fry fed with this compound feed was better than that of ordinary fish feed. High, low feed consumption, high...

Abstract

The invention provides a compound feed of pelteobagrus fulvidraco fish fry and a preparation method thereof. The compound feed comprises the following components in percentage by weight: 30-45% of fish meal, 5-8% of meat and bone meal, 15-20% of flour, 4-8% of corn, 8-15% of soy bean meal, 3-5% of rapeseed meal, 1-4% of fish oil, 10-15% of corn gluten meal, 1.0% of multivitamins, 1.0% of multiminerals, 0.1% of immunopotentiator, 0.2% of liver protecting agent, 0.2-0.4% of choline and 1-2% of calcium biphosphate. The compound feed has high quality grinding particle size, mixing uniformity, feed shaping property, water resistance and other characteristics. The pelteobagrus fulvidraco fish fry fed with the compound feed has body color close to the natural body color, and the compound feed can improve the anti-virus capability of the pelteobagrus fulvidraco fish fry, shorten the breeding cycle, reduce the breeding cost, reduce the sources of the diseases and water body pollution and has obvious economic and environmental benefits.

Description

technical field [0001] The invention relates to a compound feed for yellow catfish fry and a preparation method thereof. Background technique [0002] Yellow catfish scientific name Pelteobagrus fulvidraco (Richardson), commonly known as Huanglading, Huangyatou, etc., are distributed in all waters of the country except the western plateau. The yellow catfish body is blue-yellow, mostly with irregular brown markings, the fins are gray-black with yellow, the meat is tender, its muscles are rich in nutrients, without intermuscular spines, the meat is delicious, and the edible ratio is high. Food fish with high economic value. For a long time, the yellow catfish has been treated as a small wild fish because of its small size. With the improvement of people's living standards, the consumption of aquatic products has rapidly changed to "quality-oriented", thus re-understanding the economic value of many aspects such as the nutritional value of the yellow catfish. "The hot-sel...
